Pipe fittings with filter

Abstract

Pipe fittings with a filter contain a body, a filter valve, and two seal gaskets. The body includes a first connection pipe and a second connection pipe, a receiving orifice, and at least one guide slot. The filter valve includes a driven section and an operation portion. The two seal gaskets are accommodated in the first peripheral groove and the second peripheral groove respectively. The driven section has a first peripheral groove, a second peripheral groove, and a filtration orifice defined between the first peripheral groove and the second peripheral groove and communicating with the driven section, and at least one fixing bolt mounted between the operation portion and the first peripheral groove and extending outward from the driven section. The at least one fixing bolt slides into the at least one guide slot respectively so that the filter valve is accommodated in the receiving orifice.

What is claimed is: 
     
       1. Pipe fittings with a filter ( 30 ) comprising:
 a body ( 10 ) including a first connection pipe ( 11 ) and a second connection pipe ( 12 ) which are connected on two ends of the body ( 10 ) respectively, a receiving orifice ( 13 ) defined between and communicating with the first connection pipe ( 11 ) and the second connection pipe ( 12 ), and at least one guide slot ( 14 ) formed on the receiving orifice ( 13 ), wherein the receiving orifice ( 13 ) is cylindrical and has at least one opening defined on one of two ends of the receiving orifice ( 13 ); 
 a filter valve ( 20 ) including a driven section ( 21 ) and an operation portion ( 25 ) arranged on an end of the driven section ( 21 ); and 
 two seal gaskets ( 27 ) accommodated in a first peripheral groove ( 22 ) and a second peripheral groove ( 23 ) respectively; 
 wherein the driven section ( 21 ) has the first peripheral groove ( 22 ), the second peripheral groove ( 23 ) which are defined on two sides of the driven section ( 21 ) respectively, and a filtration orifice ( 24 ) defined between the first peripheral groove ( 22 ) and the second peripheral groove ( 23 ) and communicating with the driven section ( 21 ), 
 wherein: 
 at least one fixing bolt ( 26 ) mounted between the operation portion ( 25 ) and the first peripheral groove ( 22 ) and extending outward from the driven section ( 21 ), wherein the at least one fixing bolt ( 26 ) slides into the at least one guide slot ( 14 ) respectively so that the filter valve ( 20 ) is accommodated in the receiving orifice ( 13 ), 
 wherein the at least one guide slot ( 14 ) is open and is formed on the at least one opening of the receiving orifice ( 13 ); 
 wherein the at least one guide slot ( 14 ) have a guide surface ( 142 ) and at least one positioning projection ( 141 ), the at least one positioning projection ( 141 ) is adjacent to at least one bottom of the at least one guide slot ( 14 ) to form a mounted slot for fixing and stopping a removal of the at least one fixing bolt ( 26 ), an opening of the mounted slot is formed between the at least one positioning projection ( 141 ) and the guide surface ( 142 ), a contour of the mounted slot is an arc shape when viewed in cross-section; 
 wherein, when the at least one fixing bolt ( 26 ) is fixed into the mounted slot, the contour of the mounted slot and a portion of a contour of the at least one fixing bolt ( 26 ) are completely in contact with each other, a portion of the at least one fixing bolt ( 26 ) is outwardly protruded from the opening of the mounted slot, a portion of the at least one fixing bolt ( 26 ) inside the mounted slot is larger than the opening of the mounted slot when viewed in cross-section; 
 wherein, the guide surface ( 142 ) of the at least one guide slot ( 14 ) is used to press against the at least one fixing bolt ( 26 ) and guide the fixing bolt outwardly when the filter valve ( 20 ) is removed from the receiving orifice ( 13 ) and enables the at least one fixing bolt ( 26 ) to be removed from the mounted slot. 
 
     
     
       2. The pipe fittings as claimed in  claim 1 , wherein the filter ( 30 ) is accommodated in the filtration orifice ( 24 ) of the driven section ( 21 ), such that fluid flows between the first connection pipe ( 11 ) and the second connection pipe ( 12 ) and is filtered by the filter ( 30 ). 
     
     
       3. The pipe fittings as claimed in  claim 2 , wherein the filter ( 30 ) is removably accommodated in the filtration orifice ( 24 ). 
     
     
       4. The pipe fittings as claimed in  claim 3 , wherein the filtration orifice ( 24 ) has at least one support rib configured to support the filter ( 20 ). 
     
     
       5. The pipe fittings as claimed in  claim 4 , wherein the filtration orifice ( 24 ) has multiple horizontal support ribs ( 241 ) and multiple vertical support ribs ( 242 ) perpendicular to the multiple horizontal support ribs ( 241 ). 
     
     
       6. The pipe fittings as claimed in  claim 4 , wherein the receiving orifice ( 13 ) has a recess ( 15 ) defined on at least one opening of one of two ends of the receiving orifice ( 13 ) adjacent to the second connection pipe ( 12 ). 
     
     
       7. The pipe fittings as claimed in  claim 2 , wherein the filter ( 30 ) is one-piece formed in the filtration orifice ( 24 ). 
     
     
       8. The pipe fittings as claimed in  claim 1 , wherein the receiving orifice ( 13 ) has two guide slots ( 14 ) formed on two sides of the at least one opening of the receiving orifice ( 13 ), and the two guide slots ( 14 ) correspond to two fixing bolts ( 26 ) individually. 
     
     
       9. The pipe fittings as claimed in  claim 1 , wherein a diameter of the driven section ( 21 ) is more than that of a connection portion between the first connection pipe ( 11 ) and the second connection pipe ( 12 ). 
     
     
       10. The pipe fittings as claimed in  claim 1 , wherein the contour of the at least one fixing bolt ( 26 ) is a circle shape when viewed in cross-section.
